Ok, still kinda new, so I hope this is the right section.. Got a Provari 2.5, came with the Protank 2. I got tired of the Protank constantly leaking, tasting burnt, inconsistent heads right out of the package, yada yada yada. I decided I wanted to try a rebuildable(RTA) tank atty. Instead of buying the Russian 91%, and finding I didn't like it or whatever, I went with something cheaper to get my feet wet first. Enter the Prometheus clone.... Im attatching pics for all this in the order discussed, just FYI. Anyway, I bought some 32 ga. Kanthal wire, and some organic cotton balls, and had at it. My first two coil attempts using a 3/32 drill bit sucked, so I made a tool for winding coils. I took a small hobby(for my RC cars and trucks) allen driver which had a .073 shank and drilled a hole through the taper on the handle very close to the shaft of the tool. I put one end of my wire in the hole, use the marks on the tool as a reference, and twist the tool in my fingers until my desired number of wraps is achieved. I made a dual coil setup with a resulting 2 ohm resistance, and Im vaping it on my Provari with 4.5 volts with 70/30 juice. Im seriously loving this thing, and cant wait to get my Russian 91!!!!!
